Capacitive proximity sensing is a key feature for many smart devices and equipment. In this application note, we review several important advantages of our new capacitive sensing chip FDC2x1y, which is based on an LC resonator. They include its high resolution, immunity to electro-magnetic interference (EMI), and tolerance of high offset capacitance. We also provide some guidelines in sensor desi - Power Consumption Analysis for Low Power Capacitive Sensing ApplicationsPDF, 116 Kb, 档案已发布: Jan 18, 2016
